  1. Notes: Data testing tape pick-up efficiency, larval hatch rate based on first and second submergence of tapes from egg pick-up and adult emergence from successfully reared larvae (including controls)
  2. aExposure: no. of days that eggs were exposed to the tape
  3. Abbreviations: n, total egg pick-up across all samples; SD, standard deviation from the percentage mean; na (within egg pick-up) where eggs were hatched directly from filter paper controls; na (within adult emergence) where no adults could emerge due to zero hatch-rate scores
